2 Claims.

This application is a refile of my abandoned application, Serial No. 532,387, filed on April 23, 1931.

My invention relates to connectors for temporarily connecting a tube or spigot from which liquid or gas is to be drawn with a tube through which the liquid. or gas is to be delivered. My invention is particularly adapted for use in laboratories where a reagent in solution is to be drawn from a container into a beaker containing a substance in solution or in solid form which is to be subjected to the action of the reagent. The reagent to be used is often to be drawn from the container through a glass tube and it is a matter of more or less diiliculty to properly connect this glass tube and the tube through which the reagent is to be delivered to the beaker, and it sometimes happens that in attempting to make the necessary connection the hand of the operator is injured by contact with the glass tube or by contact with the reagent.

It is the object of my invention to provide a simple, inexpensive device by which satisfactory temporary connection may be made with the glass tube or spigot through which the reagent is supplied and a delivery tube without danger of having the hand of the operator come in contact with the glass tube or spigot or have any of the reagent spilled upon his hand.

With the objects above indicated and other objects hereinafter explained in view, my invention consists in the construction of the connecter hereinafter described and claimed.

Referring to the drawing:

Figure 1 is a front view of a device embodying my invention, partly broken away, showing the device in use.

Figure 2 is a rear view of the device shown in Figure 1.

Figure 3 is a side view of the same, and

Figure 4 is a cross section on line 4-4 of Figure 1.

In the drawing I indicates the the connecter formed of a single piece of sheet material such as metal, hard rubber or any material capable of being rolled or bent into conical form. This single piece of sheet material is rolled or bent into the shape of a cone tapered from above downward with the upper portion 2 of its edges brought nearly into contact but not secured together and with the lower portions 3 of its edges cut away so as to leave considerable space between them. The sheet material used should be somewhat resilient and the cone into which it is formed should taper at its lower end to a size adapted to have the material of the delivery tube 4 of rubber or other elastic material to be readily drawn over it as shown. At its upper edge in the rear or on one side the cone is preferably provided with a projecting ear 5 against which the hand of the operator may rest in lifting the device into contact with the glass tube or spigot 6.

The cone being of a diameter at its upper end much greater than the diameter of the glass tube or spigot 6 the cone may be so raised that the lower end of the tube or spigot 6 will extend to near the lower end of the cone the extent to which it will reach depending upon its diameter. When thus raised into position by one hand of the operator his other hand is free to operate the valve or other controlling means of the tube or spigot and may be held in position without risk of injury from contact with the spigot or with the reagent. By leaving the edges along the portion 2 separated the expense of the usual soldered or other joint is avoided and the funnel is left adjustable so as to fit spigots or supply tubes of varying diameters, and because of this construction the cross sectional shape may be so modified as to avoid its fitting the spigot or supply tube too closely to permit escape of air. By cutting away the lower portions 3 the extreme lower end of the funnel is so reduced in area as to readily enter the end of the delivery tube which is to be pulled over it.

Having thus described my invention, what I claim is:

1. A connecter for connecting a tube or spigot to a delivery tube of elastic material consisting of a single piece of sheet material bent into conical form with the upper portions of its adjacent edges nearly in contact and with the lower portion of said edges cut away so as to leave considerable space between them and to form a conical extension adapted to receive the end of the delivery tube.

2. A connecter for connecting a tube or spigot to a delivery tube of elastic material consisting of a single piece of sheet material bent into conical form with the upper portions of its adjacent edges nearly in contact and with the lower portion of said edges cut away so as to leave considerable space between them and to form a' conical extension adapted to receive the end of the delivery tube, the piece of sheet material being provided at its upper end with an outwardly extending projector adapted to rest against the hand of a person using the connecter.
